Gernetic: Epidermis


Eighty to ninety percent of the epidermal cells are in various stages of differentiation.

At any given time, 40% of the basal keratinocytes are undergoing mitosis (division).

Cells in the basal layer divide, migrate upwards, differentiate and die.

The stratum corneum is pliable, essentially waterproof and should be highly resistant to the environment.

In a healthy and optimally functioning mature skin, cells in the epidermis live for 4-6 weeks before being shed.

Immuno may be used in association with Mito Special to enhance or restore this process as part of the skin immunity treatment.

The mid layers of the epidermis (spinosum/granulosum) produce large amounts of keratin (fibrous protein).

This creates a barrier zone between living and dying keratinocytes, limits the permeability of the skin and reduces UV penetration.

The epidermis contains no blood vessels, nutrients and wastes are transferred by the papillary dermis.
